This comparison identifies at least one related event among the plurality of detected events, so that the detected event can be filtered to determine the related event.
Japanese Unexamined Patent Application Publication No. 2009-086762 discloses a similarity calculation device that calculates the similarity of a plurality of color images. That is, the two color images are divided into a plurality of predetermined common areas between the color images, and a feature amount for each primary color in each divided area is derived. Then, the degree of similarity is calculated by adding a value based on the difference in feature quantity for each primary color between the same divided areas to all the divided areas.

However, in the configuration according to each of Patent Documents 1 to 3 described above, the data management needs to register in advance the data name, property structure name, each property information, etc. (hereinafter referred to as data specific information). Therefore, in order to manage many types and a large amount of data, there is a problem that there is a lot of data specific information to be registered and it is very inconvenient.
In addition, when viewed from an application that uses data, it means that data cannot be used unless the data specific information of the data used by the user is registered in advance. For this reason, there is a problem that data cannot be used easily.

An embodiment of the present invention will be described. The outline of the data information management system according to the present invention is as follows. That is, the data information management system manages data from a plurality of data acquisition means (hereinafter referred to as actual data) with abstracted and integrated data, and provides structured data in response to requests from various applications. . Taking a camera or RFID (Radio Frequency IDentification) as an example of data acquisition means, actual data from these cameras and RFID are abstracted and managed by integrated structured data. The structured data used in the present invention will be described later.
For example, in the field of physical security, when an application manages the movement of a person in a store or the like, a large amount of high-precision and wide-range information about the person is required. Since there is a blind spot area in the camera, it is possible to obtain a large amount of a wide range of information about the person by supplementing the information of the person in the blind spot area with the information from the RFID. Further, by using the camera information and the RFID information redundantly, it is possible to acquire highly accurate position information of the person.
Note that when the object is specified as “person”, information other than the person (for example, information on products, etc.) is unnecessary information. In addition, in order to manage actual data from a plurality of types of data acquisition means, it is necessary to register data specific information of each actual data in advance. Therefore, in the configuration in which the data unique information of many types and a large amount of data is registered in advance, a huge amount of registration work is required and lacks convenience.
Therefore, the data information management system manages actual data by converting it into structured data specialized for objects such as persons.
The structured data is data structured with the property information of the object, and has a hierarchical structure as shown in FIG. 3, for example. That is, when the object is “person”, the data related to the person is hierarchical data.
On the other hand, in the following description, the terms reference data format information and structured data format information (or structured data format information) are used. These are information indicating the format (structure) of the data, and are constituted by property names of the data instead of the actual data.
For example, FIG. 3 shows structured data, and FIG. 4 shows structured data format information. In FIG. 3, the property value 52a is a numerical value “100”. On the other hand, the property value 91b shown in FIG. 4 is “coordinate (x)”. “Coordinate (x)” does not indicate specific information, and the property value 91b indicates that the property contains data defined by the name “coordinate (x)”.
In this way, since the actual data is converted into structured data and managed, there is no need to register the unique information of the actual data in the data information management system. Therefore, data management can be easily performed. In addition, even for an application that uses structured data managed by this data information management system for the first time, it is possible to obtain the corresponding structured data simply by sending the necessary structured data format information. . That is, the application can easily use structured data without knowing data-specific information of the type of data acquisition means (camera, RFID, etc.).
<First Embodiment>
A first embodiment of the present invention will be described. FIG. 1 is a block diagram of a data information management apparatus 1 according to the present embodiment. The data information management device 1 includes a transmission / reception unit 2, a coincidence determination unit 3, and a registration / reading unit 4.
The transmission / reception unit 2 receives the structured data registration request command or the registered structured data provision request command set in the property structure of the preset object, and receives the structured data corresponding to the provision request command. Output.
The match determination unit 3 detects reference data format information that matches the property structure of the received structured data from the plurality of reference data format information, in which a plurality of reference data format information related to the object is preset.
When the transmission / reception unit 2 receives the registration request command, the registration / reading unit 4 registers the received structured data in a storage area allocated in advance to the reference data format information detected by the match determination unit 3. When the transmission / reception unit 2 receives the provision request command, the registered structured data is read from the storage area previously assigned to the reference data format information detected by the coincidence determination unit 3 and output to the transmission / reception unit 2. To do.
That is, when the transmission / reception unit 2 receives a registration request command, it determines whether the format information of the structured data to be registered matches the reference data format information registered in advance. Then, the received structured data is registered in the storage area allocated for the matched reference data format information.
On the other hand, when the transmission / reception unit 2 receives the provision request command, it determines whether the structured data format information included in the provision request command matches the reference data format information. Then, the structured data is read out from the storage area assigned to the matched reference data format information and output.
Thus, since actual data is converted into structured data and managed, it is not necessary to pre-register data specific information in the data information management system, and data management is facilitated. In addition, the application can easily use structured data without knowing data-specific information of the type of data acquisition means (camera, RFID, etc.).
<Second Embodiment>
Next, a second embodiment of the present invention will be described. FIG. 2 is a block diagram of a data information management system 10A according to the second embodiment. The data information management system 10A includes a data information management device 20A, an analysis engine device 14, and a storage device 13.
The data information management device 20A includes a transmission / reception unit including an application-side transmission / reception unit 21 and an engine-side transmission / reception unit 27, a coincidence determination unit 24, a coincidence determination unit including a reference data storage unit 25 for storing reference data format information, and a storage unit correspondence table. 22 and a registration / reading unit including a registration / reading unit 23.
The data information management system 10A allows the analysis engine device 14 to analyze actual data such as position information, speaker information, and voice-recognized keywords from a plurality of types and data acquisition means such as a large number of cameras and RFIDs. The structured data obtained as described above is stored and managed, and the stored structured data is provided in response to a request from the application group 11.
<Analysis engine device>
The analysis engine device 14 includes a plurality of analysis engines 14a to 14k. Then, structured data is generated by analyzing the actual data signal G1 by the analysis engines 14a to 14k, and a registration request command G2 including the structured data is output to the data information management apparatus 20A.
The reason why the analysis engine device 14 is composed of a plurality of analysis engines 14a to 14k is to enable analysis according to the type of data acquisition means. For example, when a camera or RFID is considered as the data acquisition means, the actual data from the camera is two-dimensional data (including two or more dimensions), but the actual data from the RFID is one-dimensional data. Therefore, different analysis algorithms are required to analyze these actual data. Therefore, the analysis engine device 14 is provided with a plurality of analysis engines corresponding to differences in analysis algorithms and the like.
An analysis algorithm in the analysis engine is not particularly limited, but a known method that can extract data related to a preset object and its format information from actual data is applicable.
FIG. 3 is a graph of the analysis result (structured data) by the analysis engine device 14. This analysis result is composed of two structured data consisting of two types of objects of human information “Person 1” 51 and positional information “Position 1” 52 based on resource information “Analysis Result 1” 50. Has been.
The property value 51a of the personal information “Person 1” 51 is “Taro”, and the property values 52a, 52b, and 52c of the positional information “Position 1” 52 are “100”, “200”, and “200”, respectively. “300”. The property value 52a may correspond to the X coordinate value, the property value 52b may correspond to the Y coordinate value, and the property value 52c may correspond to the Z coordinate value. That is, the property values 52a, 52b, and 52c may indicate three-dimensional position information.
Now consider the actual data from the camera. In this case, even if no person exists, actual data exists. In order to manage all such actual data, it is easy to understand that enormous management capacity (storage capacity) is required, and management of each data-specific information requires a great deal of effort. Considering only data related to a person, there is little information about the person included in actual data at a certain moment. This can be easily understood if, for example, a photograph is imagined. Furthermore, for example, in a store or the like, a person does not always exist. This means that there are many actual data that will not be used in the end.
However, if information related to a specific object is structured and managed with general format information as in the present invention, it is not necessary to manage unnecessary actual data. There is an advantage that the data processing load becomes very small.
In this embodiment, human information and positional information are described as examples of objects, but objects are items that can be set in advance by a system administrator or the like.
<Application group>
The application group 11 includes a plurality of applications 11a to 11m that use registered structured data stored in the storage device 13. Then, the application group 11 outputs a provision request command G7 for requesting provision of structured data to the data information management apparatus 20A. Further, the application group 11 receives an information provision signal G12 including structured data corresponding to the provision request command G7 from the data information management apparatus 20A.
FIG. 4 is a graph of structured data format information included in the provision request command G7 output from the application group 11. In this structured data format information, the position information “postion” 91a of the person “person1” 91 is represented by the coordinates x, y, z “coordinate (x), (y), (z)” 91b to 91d. Have. In other words, the application group 11 requests the provision of structured data having such format information.
On the other hand, FIG. 5 is a graph of structured data included in the information providing signal G12 output to the application group 11. The structured data includes coordinate information “position1,” “position1” 92a with coordinate values “x, y, z” 92b, 92c, and 92d “10”, “20”, “30” regarding the person “person1” 92. “X, y, z” 92f, 92g, and 92h includes two pieces of position information “position 2” 92e, which are “100”, “200,”, and “300”.
That is, in response to the request for the structured data format information shown in FIG. 4, two structured data having different position information are provided. This means that all pieces of corresponding structured data can be provided for one (one type) of structured data format information. Therefore, the application can efficiently collect structured data.
<Engine side transceiver>
The engine-side transmitting / receiving unit 27 receives the registration request command G2 from the analysis engine device 14. At this time, information included in the registration request command G2 is structured data, and information used by the coincidence determination unit 24 is structured data format information. Therefore, the engine-side transmitting / receiving unit 27 generates structured data information from the structured data included in the registration request command G2, and outputs this to the match determination unit 24 as a match determination command G3. The engine-side transmission / reception unit 27 may output the structured data to the coincidence determination unit 24 as the coincidence determination command G3, and the coincidence determination unit 24 may generate a structured data format to perform the coincidence determination process. .
Further, the engine-side transmitting / receiving unit 27 receives the determination result from the match determining unit 24 as a match determination result signal G4, and outputs this as a registration execution command G5 to the registration / reading unit 23.
<Application side transceiver>
The application-side transmitting / receiving unit 21 receives a provision request command G7 for requesting provision of structured data from the application group 11. Then, the application-side transmitting / receiving unit 21 outputs the structured data format information included in the provision request command G7 to the match determination unit 24 as a match determination command G8.
In addition, the application-side transmitting / receiving unit 21 receives the determination result from the match determination unit 24 as a match determination result signal G9 and outputs this as a search execution command G10 to the registration / read unit 23.
Further, the application-side transmitting / receiving unit 21 receives the search result from the registration / reading unit 23 as a search result signal G11 and outputs it to the application 11 as an information providing signal G12.
<Reference data storage unit>
The reference data storage unit 25 stores reference data format information set in advance. The reference data format information has a structure corresponding to the structured data format information and is structured data format information managed by the data information management apparatus.
FIG. 6 is an example of reference data format information stored in the reference data storage unit 25. The reference data format information 25A includes a plurality of types of property information 25Aa to 25Ad, and each property information 25Aa to 25Ad includes a plurality of properties 25Ba to 25Bc. For example, the property information 25Aa includes properties of a hierarchy “1”, the number of nodes “1”, and a type “resource”. Since FIG. 6 shows the standard data format information, the types “resource” and “integer value” indicate that the resource data is entered in the resource column in the actual structured data, and the integer value column indicates the integer. Indicates that the value of.
Note that the number of property information and the type of property (names such as hierarchy, number of nodes, etc.) can be set as appropriate. Such reference data format information is identified by a reference data identification number (reference data ID).
<Match determination unit>
The coincidence determination unit 24 receives the coincidence determination command G8 from the application side transmission / reception unit 21, and receives the coincidence determination command G3 from the engine side transmission / reception unit 27. The match determination command G8 includes structured data format information corresponding to the provision request command G7 shown in FIG. 4, and the match determination command G3 includes structured data format information corresponding to the registration request command G2 shown in FIG. It is included.
Then, the matching determination unit 24 searches the reference data storage unit 25 for reference data format information that matches the structured data format information, and acquires the reference data ID of the searched reference data format information. Hereinafter, the process of detecting the matching reference data format information is referred to as a matching determination process.
The coincidence determination unit 24 sends the reference data ID to the application side transmission / reception unit 21 as a coincidence determination result signal G9, and sends it to the engine side transmission / reception unit 27 as a coincidence determination result signal G4.
<Registration / reading unit>
When the registration / reading unit 23 receives the search execution command G10 from the application side transmission / reception unit 21 or the registration execution command G5 from the engine side transmission / reception unit 27, the registration / reading unit 23 stores the storage unit correspondence table based on the search execution command G10 and the registration execution command G5. 22 is searched. Then, the storage area (the storage units 13a to 13n in the storage device 13) assigned to the reference data ID included in the search execution command G10 and the registration execution command G5 is specified.
<Storage unit correspondence table>
The storage unit correspondence table 22 is a table in which the correspondence relationship between the reference data ID and the storage unit ID that is the identification number of the storage units 13a to 13n assigned in correspondence with the reference data ID is tabulated. Therefore, the registration / reading unit 23 searches the storage unit correspondence table 22 for the storage unit ID corresponding to the reference data ID read by the matching determination process.
<Storage device>
The storage device 13 includes storage units (for example, information recording devices such as hard disks) 13a to 13n that form one or more storage areas for storing structured data. As described above, each storage unit 13a to 13n is assigned a storage unit ID.
FIG. 7 is a diagram exemplifying a data structure when the structured data included in the registration request command G2 shown in FIG. The information characterized by the resource ID of “Analysis Result 1” 50 indicates that the parent resource ID, property name, and value do not have information “−”. The information characterized by the resource ID of “Coordinate_y” 52b indicates that the parent resource ID is “Position 1” 52, the property name is “Coordinate: y” 52d, and the value is “20” 52e. Yes.
Thereafter, the registration / reading unit 23 accesses the storage units 13a to 13n having the storage unit ID, registers the structured data, and reads the requested structured data. The read structured data is output to the application side transmitting / receiving unit 21.
<Match determination process>
Next, the match determination processing procedure in the match determination unit will be described. The match determination process is started when the match determination unit 24 receives the match determination command G8 from the application side transmission / reception unit 21 or the match determination command G3 from the engine side transmission / reception unit 27.
As described above, the match determination process based on the structured data format information is the same process regardless of whether the received command is the match determination command G8 or the match determination command G3. A case where G3 is received will be described as an example.
FIG. 8 is a flowchart showing the matching determination processing procedure. FIG. 9 is an explanatory diagram showing the concept of the coincidence determination process. In FIG. 9, the hatched area indicates the highest resource. The structured data format information 60 is represented by a tree 60a in which property information is graphed and a table 60b in which the property information is tabulated. Similarly, the reference data format information 70A and 70B are indicated by trees 70Aa and 70Ba and tables 70Ab and 70Bb. The reference data format information 70A is format information with positional information as an object, and the reference data format information 70B is format information with human information as an object.
The structured data format information 60 of the structured data to be registered includes three property information 61 to 63, the reference data format information 70A includes four property information 71 to 74, and the reference data format information 70B includes four property information 75 to 78. Have. The property information 61 to 63, 71 to 74, and 75 to 78 have property values corresponding to property names of “hierarchy”, “number of nodes”, and “type”, respectively.
At this time, the property information 61 to 63 does not match any of the property information 71 to 74. Therefore, it is determined that the structured data format information 60 does not match the reference data format information 70A according to the matching determination process described later.
On the other hand, the property information 61 and 62 completely match the property information 75 and 76, respectively. Further, the property information 63 completely matches the property information 77 and 78. That is, the reference data format information 70B includes the structured data format information 60. Therefore, it is determined that the structured data format information 60 and the reference data format information 70B match in accordance with a match determination process described later.
By the way, as shown in FIG. 10, the structured data format information 80 may be composed of a plurality of reference data format information 90A and 90B. In such a case, the structured data format information is disassembled for each reference data format information, and matching determination processing is performed.
FIG. 10 is an explanatory diagram showing a concept of disassembling structured data format information including a plurality of reference data format information. In FIG. 10, the hatched area indicates the highest level resource in the reference data format information.
Property information 85 to 88 of the reference data format information 90A is included in the structured data format information 80. Further, the property information 81 to 84 of the reference data format information 90B is included in the structured data format information 80. Therefore, the structured data format information 80 can be decomposed into the reference data format information 90A and the reference data format information 90B. In the match determination process, the structured data format information 80 matches the reference data format information 90A. In addition, the structured data format information 80 matches the reference data format information 90A. Under this assumption, the matching determination process will be described.
Step SA1: First, structured data format information is set in a table format. For example, as shown in FIG. 9, the structured data format information has a table 60b structure in which a plurality of property information 61 to 63 are arranged in columns.
Step SA2: Next, one piece of reference data format information is read from the reference data storage unit 25. The read reference data format information is stored in a table formation as shown in FIG.
Step SA3: The property information forming the row of the reference data format information table is to be compared. Hereinafter, the property information to be compared is referred to as comparison property information.
Step SA4: A comparison determination is made as to whether or not the comparison property information is included in the structured data format information. As a result, if the comparison property information is included in the structured data format information, the process proceeds to step SA5, and if not, the process proceeds to step SA7.
Step SA5: It is determined whether or not the comparison process has been completed for all property information of the reference data format information. If the comparison process has not been completed, the process proceeds to step SA3, the next property information is set as the comparison property information, and the above-described comparison process is performed. On the other hand, when the comparison process is completed, the process proceeds to step SA6.
Step SA6: Since all the property information of the reference data format information is included in the structured data format information, it is determined that they match, and the reference data ID included in the reference data format information is acquired.
Note that the reference data format information determined to match is not limited to one, and a plurality of reference data format information may be detected. In this case, a plurality of reference data IDs are acquired. Further, even when a plurality of reference data IDs are acquired, it is determined that one structured data format information is included in the plurality of reference data format information, and one structured data format as shown in FIG. Data format information may be decomposed and determined to be included in a plurality of reference data format information.
Step SA7: It is determined whether or not a match determination process has been performed for all reference data format information. If the match determination process has not been performed for all the reference data format information, the process returns to step SA2, and the next reference data format information is read and compared. On the other hand, if the coincidence determination process has been performed for all reference data format information, the process proceeds to step SA8.
Step SA8: It is determined whether or not at least one reference data ID has been acquired. If at least one reference data ID has not been acquired, the process proceeds to step SA9. If it has been acquired, the match determination process ends. The acquired reference data ID is output to the application side transmission / reception unit 21 as the match determination result signal G9 or output to the engine side transmission / reception unit 27 as the match determination result signal G4.
Step SA9: If no reference data ID is acquired, it means that there is no matching reference structure or data, so no matching data is output.
<Registration process>
Next, structured data registration processing will be described with reference to the flowchart of FIG. The structured data registration process starts when the engine-side transmitting / receiving unit 27 receives a registration request command G2 from the analysis engine device 14.
Step SB1: The registration request command G2 includes structured data. Therefore, the engine-side transmitting / receiving unit 27 generates structured data format information from the registration request command G2, and sends this to the match determination unit 24 as a match determination command G3. The coincidence determination unit 24 performs the above-described coincidence determination process and returns it to the engine side transmission / reception unit 27 as the coincidence determination result signal G4.
Step SB2: When receiving the coincidence determination result signal G4 from the coincidence determination unit 24, the engine-side transmission / reception unit 27 determines whether or not the reference data ID has been acquired. If the reference data ID is not acquired at this time, a signal indicating no matching data is received from the matching determination unit 24. Therefore, when a signal indicating no match data is received, the process proceeds to step SB3, and when the reference data ID is acquired, the process proceeds to step SB4.
Step SB3: If the reference data ID is not detected, information indicating that is output to the analysis requesting analysis engine device 14 for registration, and the registration process ends.
Step SB4: On the other hand, when the reference data ID is acquired, the reference data ID is included in the registration execution command G5 and sent to the registration / reading unit 23. The registration execution command G5 includes this reference data ID and structured data.
Step SB5: The registration / reading unit 23 searches the storage unit correspondence table 22 based on the reference data ID included in the received registration execution command G5, and stores the storage unit ID assigned to the reference data ID. To get. That is, the storage unit for registering structured data is specified by the storage unit ID.
Step SB6: The registration / reading unit 23 registers structured data in the storage unit of the acquired storage unit ID.
Step SB7: Thereafter, it is determined whether or not structured data is registered in the storage unit specified by all the reference data IDs. Note that all the reference data IDs in this case refer to a case where a plurality of reference data IDs are acquired by disassembling one structured data format information as shown in FIG. 10, for example.
<Search process>
Next, a search process in which the data information management apparatus 20A searches for and provides corresponding structured data in response to the provision request command G7 from the application group 11 will be described with reference to the flowchart of FIG.
This search process is started when the application-side transceiver unit 21 receives a provision request command G7 for requesting provision of structured data from the application group 11. The provision request command G7 includes structured data format information related to structured data that the application wants to use.
Step SC1: The application-side transmitting / receiving unit 21 extracts structured data format information from the provision request command G7, and outputs it to the match determination unit 24 as a match determination command G8. The coincidence determination unit 24 performs the above-described coincidence determination process and returns it to the application-side transmission / reception unit 21 as the coincidence determination result signal G9.
Step SC2: Upon receiving the coincidence determination result signal G9 from the coincidence determination unit 24, the application-side transmission / reception unit 21 determines whether or not the reference data ID has been acquired. At this time, if the reference data ID is not acquired, the process proceeds to step SC3, and if it is acquired, the process proceeds to step SC4.
Step SC3: If the reference data ID is not detected, read failure information indicating that fact is output, and the search process ends. The output of the defect information at this time is output to the application that is the request source of the structured data.
Step SC4: On the other hand, when the reference data ID is detected, the reference data ID is sent to the registration / reading unit 23 as a search execution command G10.
Step SC5: Upon receipt of the search execution command G10 from the application-side transmitting / receiving unit 21, the registration / reading unit 23 searches the storage unit correspondence table 22 and obtains the storage unit ID assigned to this reference data ID. To do.
Step SC6: Thereafter, the registration / reading unit 23 accesses the storage unit of the acquired storage unit ID and reads the registered structured data. The structured data is included in the search result signal G11 and output to the application-side transmitting / receiving unit 21. The application-side transmitting / receiving unit 21 outputs the search result signal G11 to the application group 11 as the information providing signal G12.
Step SC7: Thereafter, it is determined whether or not reading of structured data corresponding to all reference data IDs is completed.
In the above description, the match determination unit 24 performs the match determination process to acquire the reference data ID. This reference data ID is an identification number different from the storage unit ID. However, the present embodiment is not limited to this, and the reference data ID can also serve as the storage unit ID. Thus, since the reference data ID also serves as the storage unit ID, the storage unit correspondence table 22 becomes unnecessary. This means that the procedure for the registration / reading unit 23 to access the storage unit correspondence table 22 and check the correspondence relationship between the reference data ID and the storage unit ID can be omitted, and the process can be simplified.
As described above, since actual data is converted into structured data and managed, it is not necessary to pre-register data specific information in the data information management system, and data management is facilitated. In addition, the application can easily use structured data without knowing data-specific information of the type of data acquisition means (camera, RFID, etc.).
<Third Embodiment>
Next, a third embodiment of the present invention will be described. FIG. 13 is a block diagram of a data information management system including the data information management device 20B according to the present embodiment. In addition, about the same structure as 2nd Embodiment, description is abbreviate | omitted suitably using the same code | symbol.
The reference data format information described so far has been set in advance. However, there is a case where it is desired to change the reference data format information in accordance with the operation of the data information management system, a change in usage pattern, or the like. Further, there are cases where structured data that should originally be registered is not registered due to differences in expression.
Therefore, in this embodiment, a management unit or the like is provided so that the reference data format information can be added, changed, or deleted, and a conversion unit or the like is provided so that the reference data format information has a width.
FIG. 13 is a block diagram of a data information management system 10B according to the present embodiment. The data information management system 10B includes a data information management device 20B, an analysis engine device 14, and a storage device 13.
The data information management device 20B includes a transmission / reception unit including an application-side transmission / reception unit 21 and an engine-side transmission / reception unit 27, a coincidence determination unit 24, and a coincidence determination unit including a reference data storage unit 25 for storing reference data format information. A registration / reading unit including a correspondence table 22 and a registration / reading unit 23 is provided.
Furthermore, the data information management device 20B includes a conversion unit 28, a conversion data table 29, a management unit 30, and an input unit 31.
The conversion unit 28 converts the reference data format information registered in advance in the reference data storage unit 25 with reference to the conversion data table 29 that stores conversion data for converting the reference data format information.
In addition, the management unit 30 changes the conversion data stored in the conversion data table 29 and the reference data format information stored in the reference data storage unit 25 based on information input from the input unit 31 such as a keyboard. Performs addition / deletion processing. Hereinafter, changes, additions, and deletions are collectively referred to as corrections.
FIG. 14 is a diagram illustrating conversion data stored in the conversion data table 29. FIG. 15 is reference data format information before and after conversion when the reference data format information is converted based on the conversion data shown in FIG. FIG. The conversion data shown in FIG. 14 includes property names 95a, 95b, and 95c at positions X, Y, and Z (Location: x, Location: y, Location: z), and coordinates x, y, z (Coordinate: x, Coordinate: y). , Coordinate: z) is converted into property names 96a, 956, 96c. Therefore, in the graph shown in FIG. 15, the property name is changed from “Location” to “Coordinate”.
Data correction processing such as change / addition / deletion of conversion data and reference data format information is performed as follows. FIG. 16 is a flowchart showing a data correction processing procedure.
Step SD1: The management unit 30 waits for input of data correction information from the input unit 31. This data correction information includes correction data indicating specific contents to be corrected, a data type indicating whether the correction data is conversion data or reference data format information, and correction processing information indicating whether the correction is change / addition / deletion. It is out.
Step SD2: When data correction information is input from the input unit 31, the management unit 30 determines whether or not correction processing is added from the correction processing information. If it is added, the process proceeds to step SD7, and if it is not added, the process proceeds to step SD3.
Step SD3: Since the correction process is change or deletion, the management unit 30 determines whether the data to be corrected is conversion data or reference data format information based on the data type, and searches for data that is symmetrical to the change or deletion.
When the data type indicates conversion data, the management unit 30 accesses the conversion data table 29 and extracts the corresponding conversion data. At this time, the corresponding conversion data is conversion data that matches the conversion data before conversion included in the correction data (corresponding to the conversion source property name in FIG. 14).
When the data type indicates reference data format information, the management unit 30 accesses the reference data storage unit and extracts the corresponding reference data format information. At this time, the corresponding reference data format information is extracted by searching for a reference data ID that matches the reference data ID included in the correction data. In addition to searching based on the reference data ID as described above, a method of searching the information that matches the reference data format information before correction by including the reference data format information before and after correction in the correction data is also possible.
Step SD4: When the corresponding conversion data is extracted, the management unit 30 determines whether or not it is a change process from the correction process information. In the case of change processing, the process proceeds to step SD5, and in the case of deletion processing, the process proceeds to step SD6.
Step SD5: Since the correction process is a change, the correction process is performed by replacing with the corrected data.
Step SD6: Since the deletion process is performed, the corresponding conversion data is deleted from the conversion data table.
Step SD7: When the correction processing information indicates addition in step SD2, the management unit 30 determines whether the correction data is to be performed on the conversion data or the reference data format information based on the data type. In the case of conversion data, the process proceeds to step SD9, and in the case of reference data format information, the process proceeds to step SD8.
Step SD8: In this case, since the correction data is applied to the reference data format information, the management unit 30 issues a new reference data ID and allocates a storage unit corresponding to the reference data ID. Then, the issued reference data ID and the corrected data are synthesized to obtain new corrected data.
Step SD9: The management unit 30 stores the correction data in the conversion data table 29 or the reference data storage unit 25. When the correction data is stored in the reference data storage unit 25, the storage unit correspondence table 22 stores the reference data ID and the storage unit ID in association with each other.
Conversion of the reference data format information is performed during the matching determination process. The matching determination process at this time will be described with reference to the flowchart shown in FIG. The match determination processing procedure shown in FIG. 17 is the same as the match determination processing procedure shown in FIG. 8, except that steps SE1 and E2 are added.
Step SE1: Whether the comparison property information used in the comparison in step SA4 is the property information of the reference data format information stored in the reference data storage unit 25 or not, the reference data format after conversion by the conversion unit 28 Determine whether the information is property information. If it is the property information of the reference data format information after conversion, the process proceeds to step SA7. If it is the property information of the reference data format information before conversion, the process proceeds to step SE2.
Step SE2: In this step, the reference data format information is converted by the conversion unit 28. That is, if the match determination unit 24 determines that the property information of the reference data format information before conversion is not included in the structured data format information, the match determination unit 24 sends the reference data format information to the conversion unit 28. When receiving the reference data format information, the conversion unit 28 accesses the conversion data table 29 and reads the conversion data. The conversion unit converts the reference data format information based on the read conversion data and outputs it to the coincidence determination unit 24. Thereby, the converted reference data format information is set in the coincidence determination unit 24. Thereafter, the process returns to step SA3 and the above-described processing is performed.
On the other hand, if the match determination unit 24 determines in step SE1 that the property information of the converted reference data format information is not included in the structured data format information, step SA7 is executed. Since the structured data format information is not included in any of the reference data format information before and after the conversion, it is determined whether or not the reference data format information for the next determination of matching remains.
As described above, it is possible to cope with a case where the reference data format information is desired to be corrected in accordance with the operation of the data information management system, a change in usage pattern, etc., and the versatility and convenience are improved. It is possible to prevent the inconvenience that it is determined that there is no reference data format information that matches the structured data format information of the structured data that should be registered originally due to differences in expression.
Note that the above-described method can be coded into a program so as to be executable by a computer, and the program can be recorded on an information recording medium.
